Preservatives, Antimicrobials & Antioxidants

Ingredients whose recorded CosIng function is to keep a formulation stable: preservatives and antimicrobials that inhibit the growth of micro-organisms, antioxidants that slow oxidation, anticorrosives, and chelating agents that bind metal ions. The preservatives permitted in EU cosmetics are listed in Annex V of the Cosmetics Regulation; where CosIng records a restriction, the monograph shows it. 98 ingredients from the free INCIDB sample whose recorded CosIng functions place them here, 94 of them with a CAS number in CosIng. 43 carry a CosIng restriction; 1 is an Annex III fragrance allergen; 3 have an authored comedogenic grade. Membership is read from the data, not assigned by hand — an ingredient with no CosIng function has no monograph, because there would be nothing to say about it.
